Being an adult is synonymous with learning something new every day, I think we’re never taught to live alone, there are many things you never know and have to learn along the way.
For me the internet has been a great help, when I don’t know how to do something I search online for it, read a little and give it a go.
I confess that I still feel scared every time I have to change a lightbulb or anything relating to electricity.
